Here are more things to consider when purchasing eyeglasses for children:

5. Spring Hinges - A nice feature to look for is temples with spring hinges. These special hinges allow the temples to flex outward, away from the frames, without causing any damage. Moreover, spring hinges can help prevent the need for frequent adjustments and costly repairs.

6. Lens Material - Children’s eyeglass lenses should be made of polycarbonate or Trivex, because they are the most impact-resistant material around. In addition to being the safest materials, they also are lighter in weight than regular plastic lenses, a nice advantage for strong prescriptions. Polycarbonate and Trivex have built-in protection against potentially damaging ultraviolet (UV) rays, and the lenses are more scratch-resistant than regular plastic.

7. Sports Eyewear - Although polycarbonate is the lens material used for sports eyewear, regular eyeglass frames do not provide enough protection from large objects such as balls and flying elbows. So if your kid is involved in sports, a proper sports goggle with polycarbonate lenses will provide the most protection against eye injury. Although it sounds counter-intuitive, a sports goggle should have a larger vertical eye opening, rather than a smaller one. If an impact should occur and the goggles are pushed toward the face, a large eye opening keeps the impact points far above and far below the eyes.

8. Warranties - Cornerstone Eye Associates offers an optional $35 “no fault warranty” plan that will replace eyewear at 50% off regular retail pricing in case of lost or stolen glasses. Consider opting for the warranty, especially if your child is a first-time wearer.

9. Backup Pair - If your child’s poor vision causes difficulty functioning without glasses, you may want to purchase a backup pair of glasses, in case something happens to the primary pair. Prescription sunglassses can double nicely as a spare pair of glasses.

A cylinder measurement is necessary if your lens corrects for astigmatism (the cornea has an oval, rather than a round shape). Measured in diopters (a unit for refractive power of lenses), the cylinder shows how much astigmatism you have. The negative sign means myopic astigmatism (inability of the eye to focus sharply on distant objects). A plus sign would mean hyperopic astigmatism (inability of the eye to focus sharply on nearby objects).

Here are things to consider when purchasing eyeglasses for children:

1. Lens Thickness - The primary consideration in choosing glasses is always the prescription. If the prescription calls for strong lenses that are likely to be thick, it is important to keep the frames as small as possible to reduce the final lens thickness.

2. Frame Choice - Children can be made to feel more comfortable about wearing glasses when they are allowed to play a large part in choosing their own frames. Try to keep in mind that the real object is to get your child to wear the glasses. Extra enticement can be found in cool features like transitions lenses with tints that darken outdoors, which may help inspire the child to want to wear his/her glasses.

3. Plastic Vs. Metal - Children’s frames are made of either plastic or metal. Many manufacturers copy adult styles for children’s frames and kids may be attracted to these styles because they are more grown-up looking.

4. Proper Bridge Fit - One of the toughest parts about choosing suitable frames for kids is that their noses are not fully developed, so they don’t have a bridge to prevent plastic frames from sliding down (manufacturers recognize this difficulty with plastic frames and make their bridges to fit small noses). Metal frames, however, are usually made with adjustable nose pads, so they fit everyone’s bridge. It is important that the glasses stay in place, because kids tend to look right over the tops of the lenses instead of pushing slipping glasses back up where they belong.

Diameter is the distance, in millimeters, from one edge of your contact lens to the opposite edge. This measurement is very important, because it determines where on your eye the edges of the CL will rest. If the diameter is wrong, irritation or abrasion can result.

 Glare is defined as a visual condition in which the observer feels either discomfort and/or exhibits a lower performance in visual tests (e.g. visual acuity or contrast sensitivity). This is produced by a relatively bright source of light–called the glare source–within the visual field. A given bright light may or may not produce glare depending upon the location and intensity of the light source, the background luminance, the state of adaptation of the eye or the clarity of the media of the eye. Although the term “glare” is used many times in a general sense, there are actually four different types of glare. The fourth type of glare is Distracting Glare. Distracting Glare is primarily an annoyance created by light reflecting off the surface of a lens, or internally reflecting within a spectacle lens. This kind of glare may cause eye fatigue, annoyance and distraction. It is also experienced at night around headlights or street lights. An anti-reflective treatment is the solution for this problem.For further information or to book an appointment please call any of our three Rochester, NY Cornerstone Eye Associates locations in Gates (585-328-0153), Brighton (585-244-2200) or Irondeqouit (585-266-7880).

The back curvature of a contact lens is measured in millimeters. for best fit, eye comfort and health, the CL base curve is prescribed to match or compliment the curvature of your cornea (the clear covering over the front of your eye). The lower the base curve number, the steeper the curve of the cornea.

Although the term “glare” is used many times in a general sense, there are actually four different types of glare. The third type of glare is Discomforting Glare. Discomforting Glare occurs due to changing light conditions and can cause squinting, eye fatigue or may even make your eyes water. Photochromic lenses can eliminate this type of glare.

Dry eye symptoms can be a major contributing factor to CL dropout. Symptoms may result from either dry eye, a tight-fitting lens or from sensivity to a particular lens care product. Lubricating/rewetting drops may help to relieve symptoms or they make them mor pronounced depending on the dosage and types of drops chosen. it is best not to confuse artificial tears with contact lens rewetting drops. Artificial tears may contain preservatives that are contra-indicated for soft contact lens use. However, patients may safely use most preservative-free artificial tears over their soft contact lenses. Rewetting drops that are made specifically for CLs are most times best.

Although the term “glare” is used many times in a general sense, there are actually four different types of glare. The second type of glare is Disabling Glare. Disabling Glare is caused by light too bright for the eye and reduces/blocks vision due to retinal veiling (this is like a veil or haze over the retina). The solution for this type of glare is fixed tint or photochromic lenses.

Many patients who would like to try contact lenses are concerned that they won’t be able to get the lenses into their eyes. Although it can appear difficult and daunting at first, most people soon get used to the idea of putting in out taking contact lenses out of their eyes. And, of course, when you go for your CL fitting appointment (or soon after) you will be shown simple methods for inserting and removing your lenses. If millions of people can do it everyday then so can you. Also another misconception regarding CLs is that they are painful to wear. This is absolutley false. Most people experience some slight discomfort when they first begin wearing lenses, but this usually lasts only a few minutes. Modern soft contact lenses are easy to wear and so comfortable that, ideally, you will not notice you are wearing lenses at all.
